Inventor 0. E. C'df/50/7 Aiiumeys Patented June 29, 1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a new improvement in building structures and particularly to an improved wall construction and improved roof construction and an improved ceiling construction,

;,5 all arranged to agree in general formation 50 that one part will readily cooperate and interfit into the other part to make a complete construction.

Further the invention consists in the provision (to of novel means in'enabling the use of precast wall,

roof and floor building units of reinforced concrete to'the end thatthe use of much of the elaborate and expensive temporary form work heretofore commonly used in building concrete .i-lg structures is dispensed with.

The invention, together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings, wherein:

Figure 1 is an enlarged sectional view through a portion of a building constructed in accordance with thepresent invention.

Figs. 2 and-3 are-edge elevational views taken substantially on the lines 22 and 3-3 respectively, of Fig. 1.

Fig. 4 is a detail vertical sectional view showing a modified form of roof structure.

Fig. 5 is an enlarged fragmentary detail sectional view showing the manner of joining two adjacent concrete slabs together.

Fig. 6 is a fragmentary horizontal sectional view through a building structure at an outer corner of the latter.

Fig. '7 is a view similar to Fig. 6 and illustrating an inner corner construction.

Referring to the drawings by reference numerals, and in accordance with the present invention, I provide a number of pre-cast reinforced concrete unit plates or slabs 5 and B respectively.

The slabs 5 are preferably of a length correponding to the full heighth of the building, while the slabs 6 are of a length corresponding to the width or depth of the structure as may be found desirable.

Each of the slabs 5 has one longitudinal edge which is provided with an integral reinforced concrete rib or flange I as is also each slab 6, the reinforced rib or flange of each slab 6 being 50 indicated by the reference numeral 8.

At the junction of a plate 5 and its rib l and extending for the full length of the plate, said plate is provided with a rabbeted or grooved edge 9 while the opposite longitudinal edge of 55 the plate 5 is beveled as at It to conformably fit into the groove :9 of the next adjacent plate 5 I as clearly shown in Fig. 2.

Each of the plates 6 is laterally extended be- I yond its rib or flange 8 and at the edge thereof is rabbeted or otherwise provided to provide a groove vll with which is engaged the squared longitudinalfree edgeof the next adjacent plate or slab fi as shown in Fig. 3.

As shown in Figs. 1, 2, 5, 6 and '7, the slabs 5 are preferablyresorted to for forming the vertical walls or partitions of the building with the rib I thereof disposed perpendicularly. With the slabs positioned and interlocked as shown, they provide a smooth outside wall surface to which is applied a finishing coat l2 of cement plaster o or thelike.

Embedded in, or otherwise made permanent with orintegral with the free edges of the rib 1 of the slabs 5 and extending for the full length of the rib! are wood strips 13 to which are nailed the plaster lathes l4:for use in providing plaster inner wall surfaces for the building.

Where desired, and as suggested in Fig. 5, there may be provided at the joint between adjacent slabs or plate units 5 poured or run-inplace molding strips l5 in which are embedded at intervals, tie wires 16 engaged with loops reinforcing wires I! provided in the slab units 5 and ribs 1, as clearly shown in Fig. 5. Thus through the medium of the loop wires H, the tie wires I6, and the molding strips l5 a positive and efiicient joint is provided between adjacent plate units 5.

In Fig. 6 is detailed a section of an outer corner of a building constructed of the slabs 5. As shown, at each corner there is provided a precast reinforced concrete corner strip i3 having two right angularly disposed sides, the strip l8 being segmental in cross section and having integral with its convex side, an inwardly extend ing rib or flange I9, there being provided at the junction of the strip l8 and the rib ill at opposite sides of the rib, grooves 20 to accommodate the beveled edges of the adjacent slabs 5. At its free edge, the rib I9 is provided with a V-shaped groove into which is fitted and united with the rib 19, a wood strip 2| grooved as at 22 to receive the ends of the lathes I4 in a manner clear- 1y shown in Fig. 6.

Fig. 7 is a section through an inner corner, or in other words, through the corner joint between two right angularly related interior walls or partitions which latter are formed of slabs 5 as shown. In this form of corner construction, the end-most slab 5 of one wall intermediate its longitudinal edges is provided with a groove 23 to receive the beveled free longitudinal edge of the end slab of the right angularly related wall. Preferably the slabs 6 are used for forming the floors 24 and roof 25.

In forming either the floor 2d or the roof 25, or both, the slabs 6 are arranged with the free longitudinal edge of each slab engaging in a groove ii in the next adjacent slab while to the lower free longitudinal edges of the ribs 8 there are secured in any suitable manner and positively united with the ribs, Wood strips 26 to which are nailed the-lathes 21 used in constructing the plaster ceiling.

, Also in forming the floor 2 3, strips 28 are pro-- vided with ribs 29 received in the grooves l l and to the strips 28 are secured in the usual manner, the wood flooring 3d. See Fig. 3. 1

For supporting the floors 2- and the roof 25, if desired, resort may be had to poured or runin-place reinforced piers or pillows 3!.

Also at the joints between the wall slabs 5 and the ceiling and floor slabs 6 poured or runin-place reinforced concrete beams 32 are resorted to. In Fig. l is also illustrated the application of the invention in a building involving a gable roof construction, the rafters for the roof indicated by the reference numeral 33. Where such a roof construction is employed, cleats 3d of woodsor similar material are anchored to the uppermost joists 32 through the medium of anchoring bolts 35.

In Fig. 4 is illustrated the application of the invention where a tar and gravel roof is resorted to in a flat roof construction. In such a construction the top surfaces of the joists 32 and the roof slabs 6 are coated with tar 36 and over this coating of tar 35 is. laid one or more layers of roofing paper.

Also in Fig. 4, the invention is illustrated as employed where a suspended ceiling 31 is resorted It is thought that the invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings, and without requiring a more detailed description thereof.

Having thus described the invention, what is claimed as new is:-

1. In a building structure, a wall comprising a plurality of vertically disposed concrete slabs, each comprising an outer panel and an inwardly extending right angled flange adjacent one edge thereof, said slabs being rabbeted along the corner of the flanged edge thereof, respectively, and the panel of one slab fitting at its free edge into the rabbet of the adjacent slab and forming together with the flange of said adjacent slab right angled inner faces for said wall, a concrete strip extending along the angle formed by said faces and integral therewith, and reinforcing wires extending through said strip laterally and imbedded in said slabs.

2. In a building structure, a corner wall comprising right angularly related concrete slabs, and a vertically disposed corner slab extending inwardly from said corner and having an outer edge of right angled form in cross-section and opposed grooves upon opposite sides of said edge of acute angled form in cross-section, said slabs each having an edge corresponding in form to said grooves and fitting thereinto.

3. In a building structure,a floor comprising a plurality of concrete slabs each including a top panel having along one side edge an underreinforcing rib provided with downwardly convergent side walls, and a flange extending downwardly from said rib at a right angle to said panel,each

slab being rabbeted along its ribbed edge and the free edge of one panel overlapping the rabbeted edge of the adjacent panel, and sealing strips of T-shape in cross-section fitting between the overlying edges of said panels and said rabbet and overlapping said panels at the juncture thereof.
